Thumbs up WWAN fix! - 03-28-2010, 04:01 PM

If your WWAN card does not work after you upgraded you bios ("turn on hardware switch issue") here is a solution:

Tape PIN 20 of the 5530 card. This PIN is used for the (in Dell's case non-existent) hardware switch to control the radio of the card. Because of the buggy BIOS the card thinks the switch is turned off. Therefore it is impossible to turn on radio using the appropriate AT command (AT+CFUN=1).

Once PIN 20 is taped the card executes the command correctly and the Wireless connection manager (or any other equivalent software will work again).

How to find PIN 20: remove the card, turn it around (so you see the side which has no stickers). It is on the longer side, second from the key. Tape it, put the card back in and it's done.

Attached is a photo showing PIN 20.
